Students wrap rubber bands around the pegs on the 9"L x 9"W geometry board to create and study the characteristics of triangles, squares, and other polygons. Ideal for visual learners, students can also use the boards to analyze symmetry, angles, and fractions. One side of the board has a 3/4" isometric pin arrangement, while the other side has pins arranged in an 11 x 11 square array. An umbrella top on each peg keeps rubber bands in place during use. Boards are made of plastic for enhanced durability, while still being lightweight. Set includes 6 boards (1 in each color) and 54 rubber bands. Recommended for Elementary and up.
